I've been thinking about this as well. I'd like to propose "Gimbal"
as a substitute for gypsy. You could even spell it "Gymbal" if you
liked. ;-) This also has the same number of syllables and starts with
the same letter as a bonus. A gimbal is a pivoted support that allows
the rotation of an object about a single axis, so it also makes some
sense with respect to the movement being named. It is sometimes used as
a verb, as in the movement of rocket motors used for guidance, as well
as being a noun.
